THEODORE LA BRUM, OF SAN DIEGO, CALIFORNIA.

WAVE-MOTOR.

Specification of Letters Patent.

Patented Nov. 1, 1910.

Application filed June 20, 1910. Serial No. 567,810.

To all whom it may concern:

Be it known that LTnnooonn La Baum, a citizen of the United States of America, residing at San Diego, in the county of San Diego and State of California, have invented certain new and useful Improvements in ave-Motors, of which the following is a specification.

This invention relates to wave motors, and has for its object the provision of a device adapted to be actuated by the force of waves and to impart continuous rotation in one direction to a pulley or other power wheel.

A further object of the invention is the provision of improved means for anchoring a float hereinafter described and for connecting the float to the rotative mechanism.

Further objects and advantages of the invention will be set forth in the detailed de scription which now follows.

In the accompanying drawings, Figure l is a front elevation of a wave motor constructed in accordance with the invention and with the float thereof shown in partial section, Fig. 2 is a side elevation of said motor, Fig. 3 is a detail view of a ratchet and drum hereinafter described, and, Fig. l is a detail section through one end of the float.

Like numerals designate corresponding parts in all of the figures of the drawings.

Referring to the drawings, the numerals 5 designate vertical piles which support a platform 6. Vertical guide rods 7 are con nected at their upper and lower ends by plates 8 and 9. The plate 9 carries a downwardly extending bar 10 that is pivoted at 11 to a transverse rock shaft 12, this rock shaft being pivoted in bearings 13 and 14; that are carried by a float 15.

By referring to Fig. 1, it will be seen that this float 15 has hollow chambers 16 and 17 at its ends and that its central portion 18 forms a hollow cup-like chamber, for the reception of water, to thereby give the desired Rollers 20 and 21 are mounted in bearings 22 and 23 of the float, these rollers riding against the piles 5 to thereby aid in maintaining the float in proper vertical alinement with the remainder of the structure. To properly anchor the float against endwise movement and to relieve the piles 5 of much of the strain that would otherwise come against them, anchoring means are provided consisting of a pole 24 that is secured by chains or cables 25 to a short pile or other anchor 26. A cable 27 supports the upper part of the frame of the wave motor from the pole 24c and a cable'28 leads fromtlie end of the float to a strap 29 which straddles the pole 2t and carries a roller 30, said. roller bearing against the outer face of the pole as the float rises and falls. It is to be understood that the anchoring structure will be duplicated upon the opposite side of the wave motor.

Mounted in bearings 31 supported by the platform (3, is a transverse shaft 32 that carries a driving pulley Ratchet wheels 3 1 are fixed upon this shaft and are adapted to be enga ed by pawls mounted upon the ends 0 drums 3(5 and 37. Cables 38, the opposite ends of which are secured to plates 8 and 9, pass around these drums in such direction that the drums are alternately rotated in opposite directions, the pawls and ratchets being so arranged that this alternate rotation of the drums is converted into continuous rotary motion of the shaft 32 and wheel 33.

It is to be understood that the strap 29 may be made of material that will tloat, thereby aiding in supporting the cable 28. It is of course apparent that the anchoring cables from either side of the wave motor may extend to the shore or to a wharf or to any other form of anchor. Furthermore, the piles 5 may be part of a wharf structure so that the wave motor may be located directly upon a wharf if desired.

From the foregoing description, it will be seen that the present inventlon comprises simple and eflicient means for accomplishin the objects sought. The structure is e ciently anchored to resist the action of the waves, the float is provided with a water ballast compartment to give it the desired weight, and the cable carryin structure formed by the rods 7 and the plates 8 and 9, is efliciently guided in the platform 6. While the elements shown and described are well adapted to serve the urposes for which they are intended, it is to be understood that the invention is. not limited to the precise construction set forth, but includes within its purview such changes as may be made within the scope of the appended claims.

Having described my invention, what I claim is:

1. A Wave motor comprising a plurality of vertical piles, a platform supported thereon, a float mounted for vertical movement between said piles, rollers carried by said float and bearing against said piles, and inl to hold it against endwise movement, said dependent anchoring means for said float to hold it against endwise movement.

2. A wave motor comprising a plurality of vertical piles, a platform supported thereon, a float mounted for vertical movement between said piles, rollers carried by said float and bearing against said piles, and independent anchoring means for said float to hold it against endwise movement and for permitting vertical movement thereof, said anchoring means comprising a vertical pole, an anti-friction device traveling vertically thereon, and a connection between said anti-friction device and said float.

3. A wave motor comprising a plurality of vertical piles, a platform supported thereon, a float mounted for vertical movement between said piles, rollers carried by said float and bearing against said piles, independent anchoring means for said float to hold it against endwise movement, and an open Water ballast compartment located at the central portion of said float.

A wave motor comprising a plurality of vertical piles, a platform supported. thereon, a float mounted for vertical movement between said piles, rollers carried by said float and bearing against said piles, independent anchoring means for said float to hold it against endwise movement and for permitting vertical movement thereof, said anchoring means comprising a vertical pole, an anti-friction device traveling vertically thereon, and a connection between said antifriction device and said float, and an (pen water ballast compartment located at the central portion of said float.

5. A Wave motor comprising a plurality of vertical piles, a platform supported thereon, a float mounted for vertical movement between said piles, rollers carried by said float and bearing against said piles, and independent anchoring means for said float anchoring means comprising a substantially vertical pole, a distant anchor, connections between said anchor and said pole, a connec tion between the upper part of said pole and the upper part of the piles of the frame, an

anti-friction device traveling upon said pole, and a connection between said anti-friction device and said float.

6. A wave motor comprising, in combination, a frame consisting of a plurality of vertical piles, and a platform supported thereon, a vertically movable float mounted between said piles, anti-friction members carried by said float and bearing against said piles, a shaft supported upon said plat form, drums mounted upon said shaft, pawl and ratchet connections between said drums and said shaft, a vertically movable frame, a universal joint connection between said frame and said float, and cables carried by said frame and passing over said drums.

7 A wave motor comprising, in combination, a frame consisting of a plurality of vertical piles, and a platform supported thereon, a vertically movable float mounted between said piles, anti-friction memberscarried by said float and bearing against said piles, a shaft supported upon said plat form, drums mounted upon said shaft, pawl and ratchet connections between said drums and said shaft, a vertically movable frame, a universal joint connection between said frame and said float, cables carried by said frame and passing over said drums, and a centrally disposed water ballast compartment carried by said float in which said universal joint is located.

In testimony whereof I afliX my signature in presence of two witnesses.
